À trous wavelet transform is less spatial information distortion and without decimation in fusing multisensor images at same degree. Therefore, the image fused by à trous wavelet transform can get better performance than other image fusion methods. In this paper, multi-band à tours wavelet algorithm is used for multisensor images fusion with different resolution ratio at 1:3 and 1:4 respectively,...
The information which is contained in the multi-spectral and SAR images have different characteristic. Multi-spectral images contain a great deal of spectral information, whereas SAR images contain rich texture information, such as buildings and road network. SAR and TM images fusion based on the wavelet transform ensure the fusion image showing more spatial detail, not only conserving the spectral...
